    I suspect it's because Go's general philosophy is that it's better to be verbose and explicit (than terse and magical). Probably falls under "clear is better than clever" from Rob Pike's Go Proverbs: http://go-proverbs.github.io/

    I think if this feature was added, it would not be with struct tags, but with an Encoder.SetFieldTransform(json.SnakeCase) or similar setting.

    That might be quite a nice feature, actually. You could provide your own function to transform names when marshaling, and for unmarshaling it would strip punctuation and match case insensitively (because it's hard to do the reverse transform, for example should user_id go to UserId or UserID, and if the latter, how does the transform know?).

    In any case, it seems like an issue was opened proposing something like that a couple of years ago (https://github.com/golang/go/issues/23027), and Russ Cox responded that the JSON package is basically done, but you could either fork it and add the feature, or use a tool that modifies struct tags like https://github.com/fatih/gomodifytags
